A system and associated components for providing an intelligent circuit breaker being adapted to communicate with, monitor and control various devices within a commercial or residential premises. In one embodiment, the system is adapted for low cost, ease of installation and operation, and ease of manufacture. The intelligent circuit breaker may also be adapted to send data relating to sensed parameter or conditions to, and receive commands from, a user interface. Methods for operating such breakers and converting existing circuit breakers to intelligent circuit breakers consistent with the aforementioned system and components are also described.

Intelligent circuit breaker apparatus and methods

Improved form-less electronic apparatus and methods for manufacturing the same. In one exemplary embodiment, the apparatus comprises a shape-core inductive device having a bonded-wire coil which is formed and maintained within the device without resort to a bobbin or other form(er). The absence of the bobbin simplifies the manufacture of the device, reduces its cost, and allows it to be made more compact (or alternatively additional functionality to be disposed therein). One variant utilizes a termination header for mating to a PCB or other assembly, while another totally avoids the use of the header by directly mating to the PCB. Multi-core variants and methods of manufacturing are also disclosed.

A dual-core inductive device having one or more core elements and a sleeve adapted to fit over the core element(s). The device is significantly less expensive to produce than prior art transformers having similar characteristics. In one exemplary embodiment, the device includes two cylindrical cores forming a first (end) gap used to adjust the device's differential inductance independent of its common mode inductance. Similarly, a second gap is provided to adjust the device's common mode (leakage) inductance independent of its differential inductance. The substantially independent control afforded by these gaps allows for devices to be designed to simultaneously meet different sets of requirements; e.g., signal-path specifications and longitudinal inductance requirements. Methods for manufacturing the device(s), and telecommunications filter and splitter circuit applications, are also disclosed.

Controlled induction device and method of manufacturing

Improved inductive apparatus having controlled core saturation which provides a desired inductance characteristic with low cost of manufacturing. In one embodiment, a pot core having a variable geometry gap is provided. The variable geometry gap allows for a 'stepped' inductance profile with high inductance at low dc currents, and a lower inductance at higher dc currents, corresponding for example to the on-hook and off-hook states of a Caller ID function in a typical telecommunications line. In other embodiments, single- and multi-spool drum core devices are disclosed which use a controlled saturation element to allow for selectively controlled saturation of the core. Exemplary signal conditioning circuits (e.g., dynamically controlled low-capacitance DSL filters) using the aforementioned inductive devices are disclosed, as well as cost-efficient methods of manufacturing the inductive devices.
